node.js - 使用 volley 将 Json 发布到 android 中的服务器，但在服务器中仅获取 id

Question

我正在使用 mongodb 和 node.js 来构建一个 rest Api 顺便说一句我是初学者..所以我使用 express 启动了我的 localhost3000 但是当我在 android 中发布时它只给出 id 而不是内容..

喜欢

[{"_id":"59f4bb537ddb610f0c94fcd0","__v":0},
 {"_id":"59f4bca47ddb610f0c94fcd1","__v":0},
 {"_id":"59f4c5ce7ddb610f0c94fcd2","__v":0}
]

它只给出 localhost:3000/api/vehicles 中的 id

    String url = "http://10.0.2.2:3000/api/vehicles";
   try{


  JSONObject jsonObject=new JSONObject();
  jsonObject.put("UserName" , "zaid");
  jsonObject.put("Password" , "passwords");
  final String mRequestBody = jsonObject.toString();

  JsonObjectRequest jor = new JsonObjectRequest(Request.Method.POST, url, 
         jsonObject, new Response.Listener<JSONObject>() {
      @Override
      public void onResponse(JSONObject response) {
           System.out.println(response.toString());
      }
  }, new Response.ErrorListener() {
      @Override
      public void onErrorResponse(VolleyError error) {

      }
  }){
      @Override
      public String getBodyContentType() {
          return "application/json; charset=utf-8";
      }

      @Override
      public byte[] getBody() {
          try{
              return mRequestBody == null ? null : 
            mRequestBody.getBytes("utf-8");
          }catch (UnsupportedEncodingException e){
           return null;
          }
      }

      @Override
      protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {

          if(response.statusCode == 200){

          }
          return super.parseNetworkResponse(response);
      }

  };

  Volley.newRequestQueue(this).add(jor);
      }

///fire up //////////

app.listen(port);
